Machine learning provides an entirely new way to tackle one of the classic problems of applied mathematics.

Reusing yeast is an old brewer’s trick that saves time and money, but it eventually backfires. Cell biologists are trying to find out why—and the answers could conceivably combat aging as well.

In the agency’s latest grand challenge, teams competed for $2 million and a chance to shape the future of communication technology by finding a better way to carve up the radio spectrum.

What does spying mean when workplace surveillance is the norm?

The US military is without peer in its ability to project power around the world, and that’s not about to change.

“They’re all doing it: Russia, China, Iran … They’re all fighting these things called shadow wars, and they’re very effective,” says an ex-paratrooper and academic.

New techniques have made predictions more useful, and we used one to look at violence in Ethiopia since the election of Abiy Ahmed, the new Nobel Peace Prize winner.

The oldest technology for detecting trace amounts of materials remains the best.

Researchers at OpenAI have developed a new method for transferring complex manipulation skills from simulated to physical environments.

He nearly lost it all to an IED blast in Afghanistan. But a pioneering procedure changed everything.

The company’s LauncherOne system is designed to send satellites to low-Earth orbit. Does it really have the power to send a payload to the Red Planet?

Blockchain technology is changing the nature of money and organizations. We should probably start pondering the potential consequences.

The rapid response to the shootings in Halle shows how tech firms are learning from Christchurch.

The mere idea of AI-synthesized media is already making people stop believing that real things are real.

Technology makes fighting war easier and more palatable—but it dangerously changes the nature of the fight, argues a US Marine veteran.

Form Energy, Antora, and others are trying to develop very cheap, very long-lasting storage to clean up the electricity system.

Doctors say gene medicine tailored to a single person can work, but it still costs millions.

Rocket launches that leave on a regular schedule will make it much cheaper and easier to get small satellites into orbit.

An algorithm uses radio waves rather than visible light to detect what people are up to without revealing what they look like.

A black hole offers plenty of energy sources that might give life a foothold. But a NASA scientist has determined that despite what you saw in the movies, habitable conditions nearby are pretty unlikely.

Microgrids, buried lines, better building standards and more.

The Pentagon’s controversial $10bn JEDI cloud computing deal is one of the most lucrative defense contracts ever. Amazon’s in pole position to win—and its move into the military has been a long time coming.

Bans on the technology have mostly focused on law enforcement, but there’s a growing movement to get it out of school, parks, and private businesses too.
